MFMailComposeViewController发送邮件的实例
iPhone API已经提供了系统写邮件界面的接口,使用MFMailComposeViewController，用来显示界面.
项目中需要添加MessageUi.framework。头文件加入MFMailComposeViewControllerDelegate。
#import
sendMailViewController.m文件的实现：
- (void)viewDidLoad
{
UIButton *button = [UIButton buttonWithType: UIButtonTypeRoundedRect];
button.frame = CGRectMake(0, 40, 320, 50);
[button setTitle: @"Mail" forState: UIControlStateNormal];
[button addTarget: self action: @selector(sendEMail) forControlEvents: UIControlEventTouchUpInside];
[self.view addSubview: button];
}
- (void) alertWithTitle: (NSString *)_title_ msg: (NSString *)msg
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:_title_
message:msg
delegate:nil
cancelButtonTitle:@"确定"
otherButtonTitles:nil];
[alert show];
[alert release];
}
//点击按钮后，触发这个方法
-(void)sendEMail
{
Class mailClass = (NSClassFromString(@"MFMailComposeViewController"));
if (mailClass != nil)
{
if ([mailClass canSendMail])
{
[self displayComposerSheet];
}
else
{
[self launchMailAppOnDevice];
}
}
else
{
[self launchMailAppOnDevice];
}
}
//可以发送邮件的话
-(void)displayComposerSheet
{
MFMailComposeViewController *mailPicker = [[MFMailComposeViewController alloc] init];
mailPicker.mailComposeDelegate = self;
//设置主题
[mailPicker setSubject: @"eMail主题"];
// 添加发送者
NSArray *toRecipients = [NSArray arrayWithObject: @"first@example.com"];
//NSArray *ccRecipients = [NSArray arrayWithObjects:@"second@example.com", @"third@example.com", nil];
//NSArray *bccRecipients = [NSArray arrayWithObject:@"fourth@example.com", nil];
[mailPicker setToRecipients: toRecipients];
//[picker setCcRecipients:ccRecipients];
//[picker setBccRecipients:bccRecipients];
// 添加图片
UIImage *addPic = [UIImage imageNamed: @"123.jpg"];
NSData *imageData = UIImagePNGRepresentation(addPic); // png
// NSData *imageData = UIImageJPEGRepresentation(addPic, 1); // jpeg
[mailPicker addAttachmentData: imageData mimeType: @"" fileName: @"123.jpg"];
NSString *emailBody = @"eMail 正文";
[mailPicker setMessageBody:emailBody isHTML:YES];
[self presentModalViewController: mailPicker animated:YES];
[mailPicker release];
}
-(void)launchMailAppOnDevice
{
NSString *recipients = @"mailto:first@example.com&subject=my email!";
//@"mailto:first@example.com?cc=second@example.com,third@example.com&subject=my email!";
NSString *body = @"&body=email body!";
NSString *email = [NSString stringWithFormat:@"%@%@", recipients, body];
email = [email stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding];
[[UIApplication sharedApplication] openURL: [NSURL URLWithString:email]];
}
- (void)mailComposeController:(MFMailComposeViewController *)controller
didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
NSString *msg;
switch (result)
{
case MFMailComposeResultCancelled:
msg = @"邮件发送取消";
break;
case MFMailComposeResultSaved:
msg = @"邮件保存成功";
[self alertWithTitle:nil msg:msg];
break;
case MFMailComposeResultSent:
msg = @"邮件发送成功";
[self alertWithTitle:nil msg:msg];
break;
case MFMailComposeResultFailed:
msg = @"邮件发送失败";
[self alertWithTitle:nil msg:msg];
break;
default:
break;
}
[self dismissModalViewControllerAnimated:YES];
